摘要
首先简要介绍了青藏高原目前主流的4种动力学模型,即俯冲模型、碰撞模型、挤出模型和拆沉-板片断离模型.然后概述了青藏高原及其周缘地区各向异性的研究进展,展望各向异性研究的方向,并着重探讨了各向异性研究中需要重视的几个问题:1各向异性的多种来源;2各向异性与深部结构的关系;3面波等新方法的应用.为了更好地定量解释各向异性,需要了解深部结构与各向异性之间的关系,发展更加精细的研究手段.就目前来看,面波与体波的联合反演可以更好地约束各向异性的分辨率,而将地球动力学模拟等正演手段与地震波各向异性等反演手段相结合也可能是未来的趋势之一.
Tibetan Plateau is known as the roof of the world.It is a young continental-continental collisional orogenic belt.The Indian Plate and Eurasian Plate collide there together.It is of significance for us to reveal the deep characteristics of each block in the Tibetan Plateau and to understand the interior mechanism of continental deformation.This paper briefly described the current four mainstream kinetic models of Tibetan Plateau,i.e.,subduction model,collision model,extrusion model,and delamination-slab breakoff model.Followed by an overview of the research progress of anisotropy in the Tibetan Plateau and its adjacent areas,this paper discussed the future trend of anisotropy studies.Several issues need to be paid attention to in anisotropy studies:1 a variety of sources resulting in anisotropy;2 relationship between anisotropy and deep structure;3 application of the surface wave.In order to better explain the anisotropy,we have to understand the relationship between deep structure and anisotropy,finding more sophisticated research tools.For now,the surface wave and body wave inversion can be combined to better constrain the anisotropic resolution.Geodynamics simulation and seismic anisotropy may also be combined as one of the future trend.
